The specification requirements were 11,000 and 5,000 psi. We, as well as Caterpillar, checked the tensile strength and Caterpillar results were 13,500 psi and 4,^0 psi. 1 Raybestos results were 11,970 psi and 4,357 psi. In addition, Raybestos ran all of their other tests in the Caterpillar specification IeI 678 and found everything else to be within the spec ification limits. Due to the severity of the application at Caterpillar, we agreed to take this material back and replace it with material which also passed the- cross grain tensile requirement. From the work which we have done on the second shipment, we believe the low tensile might be one sheet of the original shipment. We plan to run further checks on the first shipment which you returned. On the replacement order of this material, which Caterpillar urgently needed, we shipped 170 sheets on August 17, and 66 sheets on August 21. You also rejected this material'because of low cross grain tensileT We reported that the manufacture of this material was closely supervised by the production and quality control departments. We were able to find two sheets which Quality Control had retained and the following results were obtained at Raybestos, Caterpillar, and Victor.

Kapps Page 2 September 15, 1967 * Width of the test specimen was 0.485". 0.500" was used as width in the calcualtion. Therefore, results with an asterisk (*) should be 150 lbs. higher. It is interesting to note that the Caterpillar and the re-check results of Raybestos are quite similar while the Victor results run 500 to 800 lbs. lower. It is evident that Victor results run consistently lower than the Caterpillar and Raybestos results. p Victor has run 15 checks on 7 different sheets-/ They cut samples from an adjacent area to these sheets and sent thepl to Raybestos for test. Raybestos results ran from 300 lbs. to 2,100/l.bs. higher than the Victor results,^/ln attempting to understand the very large difference in results which are listed below, we believe that it is due to a very poor cutting job of the tensile specimens. We have never seen samples cut so poorly and it has even caused the fracture of some of the sheets and delaminated them. As a gasket cutter, you should know how to cut cleanly. A-56, even though it is tough, cuts cleaner than the K-68. In examining these tensile specimens, which we pulled and are retaining, not enough pressure was used in cutting. They were cut cleanly a half to three quarters of the way through and the rest of the area was just pulled and not cut. L She Raybestos results, with one exception, in the 15 tests were above minimum. We question the low tests as this could be a defective sample, following are the results: Victor r/m Victor r/m Victor R/M 1 4-380 5090 4125 5000 2 4-680 6160 4470 5240 3 4-125 5100 4250 63OO 4 4300 5050 4l60 5020 5 4l8o 5230 4380 5155 4550 4870 6 4420 6225 4380 5100 7 4650 6060 4960 5880, After discussing the above results with Lou Crystal and Crawford Ellis, the shipment you have is satisfactory and meets the requirements of the IE"67^ specif!catioiI~'wirfch RaybestSS~certifies. V A VPD-81-0000611 V* Mr. M. H. Kapps Page3 September 15, 1967 When we were discussing the above on the phone, you raised she question of eight or nine weeks delivery on A-56, .008". In sheets 50 x 50 with a tolerance of .0015, we ship in three to four weeks and much faster if needed as an emergency shipment by Caterpillar. We have had this delivery time stated on other materials by Victor to end users which is most disturbing. This should be straightened out immediately. Very truly yours, .
